Embodiment Construction

[0008] introduce

[0009] Referring to the drawings, wherein like numerals indicate like parts throughout the several views, figure 1 is an example of a possible placement of the overflow reservoir bottle 16 and prior art bottle cap 12 and its proximity to the engine of a vehicle (not fully shown). And the cap 12 may include a lanyard 14 to prevent the user from losing the cap 12 when refilling or checking the coolant level inside the overflow reservoir bottle 16 .

[0010] see now figure 2 , which illustrates a cross-sectional view of an embodiment of a recovery lid 11 having a lower cup 50 and an upper cup 80 adjacent to the lower cup 50 . The lower cup 50 has a syncline void area delimited by an inclined lower wall 57 which surrounds the syncline void area on the first face 54 of the cup 50 . The upper wall 59 may enclose the syncline void on the second face 70 and may have a variable height, thus permitting adjustment of the volume of gas entering and leaving the overf...

Abstract

The application relates to a cap for a the overflow reservoir bottle, including a lower cup having a syncline void, said syncline void having by a wall extending above and below at least one surface of the lower cup. The cap also includes an upper cup with an anticline projection nesting adjacent to the syncline void of the lower cup, and said upper cup affixed to the lower cup, with at least onevent to permit gas to traverse the overflow reservoir bottle.

Description

technical field [0001] This invention relates to overflow cap vents. Background technique [0002] Internal combustion engines typically use engine coolant to cool and maintain the engine's operating temperature. As the coolant is directed through the engine, the coolant absorbs thermal energy from the engine, causing the coolant to expand due to thermal expansion. The expanded coolant takes up more space in the engine and any excess volume (flood) of engine coolant from the engine moves to the overflow reservoir bottle. Subsequently, the space (air volume) for the air inside the overflow reservoir bottle is reduced and any air inside the bottle is compressed. The compressed air inside the overflow reservoir may be at a higher pressure than the air outside the overflow reservoir. This pressure difference causes air to leave the bottle to equalize the air pressure between the inside and outside of the bottle. Air typically exits the overflow reservoir via the neck / cap int...
